Vegetation cover of the North of the Koryak Region (Kamchatsky Krai) and its geobotanical subdivision
Northern Koryakia belongs to two different vegetation zones: Beringian forest–tundra zone and East-Siberian larch forest subzone of the Eurasian boreal (taiga) zone. The territory of Northern Koryakia was subdivided into 3 geobotanical provinces and 14 districts. Most peculiar, the Siberian dwarf-pi...

These two vegetation types form a distinctive subalpine vegetation belt at lower elevations (up to 150–300 m). The alpine vegetation belt (up to 400–450 m) is characterized by a complex of dwarf-shrub and lichen-rich tundra communities that occur under conditions of a heat deficit and very short growing season.
